1 / 72 page ST Sitronix ST7565R 65 x 132 Dot Matrix LCD Controller/Driver Ver 1.7c 1/72 2009/09/14 F Fe ea attu urre es s Directly display RAM data through Display Data RAM. RAM capacity : 65 x 132 = 8580 bits Display duty selectable by select pin 1/65 duty : 65 common x 132 segment 1/49 duty : 49 common x 132 segment 1/33 duty : 33 common x 132 segment 1/55 duty : 55 common x 132 segment 1/53 duty : 53 common x 132 segment High-speed 8-bit MPU interface: ST7565R can be connected directly to both the 80x86 series MPUs and the 6800 series MPUs. Serial interface (SPI-4) is also supported. Abundant command functions Display data Read/Write, display ON/OFF, Normal/ Reverse display mode, page address set, display start line set, column address set, status read, display all points ON/OFF, LCD bias set, electronic volume, read/modify/write, segment driver direction selects, power saver, common output status select, V0 voltage regulation internal resistor ratio set. Embedded analog power supply circuits for Liquid Crystal driving: Booster, Regulator and Follower. Embedded Booster circuit: 2X,3X,4X,5X and 6X boost ratios are supported. Independent input (VDD2) for boost reference voltage. High-accuracy Regulator circuit: Build-in Electronic volume function for the contrast control. Thermal gradient = –0.05%/°C. Embedded voltage Follower circuit for LCD driving. Embedded R-C oscillator circuit. The external clock is also supported. Extremely low power consumption: 60uA, bare dice (using the internal power). Settings: VDD – VSS = VDD2 – VSS =3.0 V, Booster Ratio=4, V0 – VSS = 11.0 V. Display OFF and the normal mode is selected. Logic power supply : VDD – VSS = 2.4V to 3.3 V Analog Power (Boost reference voltage): VDD2 – VSS = 2.4V to 3.3V Booster maximum voltage limited VOUT= 13.5V Liquid crystal drive power supply: V0 – VSS = 3.0V to 12.0 V Wide range of operating temperatures: –30 to 85°C Package type: COG only. The chip is not designed to resist the light or to resist the radiation. Support LCD Module Size up to 2" G Ge en ne erra all D De es sc crriip pttiio on n The ST7565R is a single-chip dot matrix LCD driver that can be connected directly to a microprocessor bus. 8-bit parallel or 4-line SPI display data sent from the microprocessor is stored in the internal display data RAM and the chip generates a LCD drive signal independent of the microprocessor. Because the chips in the ST7565R contain 65x132 bits of display data RAM and there is a 1-to-1 correspondence between the LCD panel pixels and the internal RAM bits, these chips enable displays with a high degree of freedom. The ST7565R chips contain 65 common output circuits and 132 segment output circuits, so that a single chip can drive a 65x132 dot display (capable of displaying 8 columns x4 rows of a 16x16 dot kanji font). The chips are able to minimize power consumption because no external operating clock is necessary for the display data RAM read/write operation. Furthermore, because each chip is equipped internally with a low-power LCD driver power supply, resistors for LCD driver power voltage adjustment and a display clock CR oscillator circuit, the ST7565R can be used to create the lowest power display system with the fewest components for high-performance portable devices.
